AQI categories (India scale)
| AQI | Category | Associated health impact |
|---|---|---|
| 0–50 | Good | Air quality is considered satisfactory and air pollution poses little or no risk. |
| 51–100 | Satisfactory | Acceptable air quality; minor breathing discomfort possible for unusually sensitive people. |
| 101–200 | Moderate | May cause breathing discomfort to people with lung disease such as asthma, and to children and older adults. |
| 201–300 | Poor | May cause breathing discomfort to most people on prolonged exposure. |
| 301–400 | Very Poor | May cause respiratory illness on prolonged exposure; effects more pronounced for people with lung and heart disease. |
| 401–500 | Severe | Affects healthy people and seriously impacts those with existing diseases; avoid outdoor activity. |

About air quality in Mumbai
This page tracks the Mumbai, Maharashtra Air Quality Index using measurements from 25 Central Pollution Control Board (CPCB) monitoring stations, published through the Government of India's open-data portal. Right now Mumbai's AQI is 333 (Very Poor), with PM2.5 the dominant pollutant. The AQI is a single number from 0 to 500 that summarises how polluted the air is and what it means for health, built from pollutants such as fine particulate matter (PM2.5), coarse particulate matter (PM10), nitrogen dioxide, ground-level ozone and sulphur dioxide — the index reflects whichever is worst at the time.
How Mumbai's air changes through the year
As a western city, Mumbai's air depends heavily on geography: coastal locations are kept cleaner by sea breezes that disperse pollution, while inland areas see more dust in the dry season. Winters are typically moderate rather than severe, and the monsoon delivers the cleanest air, washing particulates from the sky.
What drives air pollution in Mumbai
Traffic, construction and road dust, industry and port or coastal activity are the main local sources. Sea breezes and stronger winds usually help disperse pollution, which is why coastal air often clears faster than in landlocked cities, though calm days and dry-season dust can still push readings up.
Cleaner and worse areas within Mumbai
Air quality is not uniform across a city. Among Mumbai's monitoring areas right now, the air is cleanest around Colaba, Mumbai - MPCB and worst around Bandra Kurla Complex, Mumbai - IITM — a reminder that local traffic, industry and construction can make a real difference over just a few kilometres. The live area-by-area comparison above shows where to go and where to avoid at this moment.
Best time to visit Mumbai for cleaner air
For the cleanest air, the monsoon and the months just after it are usually best in Mumbai, while the driest, stillest weeks can be worse. Check the live reading on this page before outdoor exercise or sightseeing, and keep an N95 mask handy for high-pollution days. Nearby cities with comparatively cleaner air right now include Pune, Nagpur, Navi Mumbai.
Staying safe in Mumbai's air
When the AQI is in the Good or Satisfactory range, outdoor activity is fine for almost everyone. From Moderate upward, sensitive groups — children, older adults, pregnant people and anyone with asthma or heart disease — should pace themselves outdoors, and once the air turns Poor or worse it is sensible for everyone to limit strenuous outdoor exertion, keep windows closed, run an air purifier indoors and wear a well-fitting mask outside. This is general information rather than medical advice. We only display a number when a recent station reading exists — if you see "data updating", we are waiting on a fresh value rather than showing an estimate.
